To all whom it may concern.-

Be it known that I, THOMAS E. BARROW,a citizen of the United States, residing at-Mansfield, in the county of Richland andz state of 5 Ohio, have invented certain new and guseful Improvements in Marine Motor-Torpedoes; and -I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompany ing drawings, and tothe letters and figures of reference marked thereon, which form a part of this specification.

t My invention relates to improvements in submarine automobile tprpedoes; and the object's of my invention are, first, to provide a submarine torpedo for naval warfare that can be sent through the water in any direction without being fired from a torpedo-tube; second, to construct a torpedo that can besent through the water any distance required and be exploded by coming in contact with any obstruction or at any'given time set .by-

as electricity stored within the torpedo; third,

' to construct. the shell which carries the explosive charge separate from the outer case, the same to be loaded and carried in the magazine ready foruse; fourth, to so construct the explosive shell that it will be-ignited by gs'jective point -or at a giventime by a gear mechanism operated by a clock-spring placed in the stern orrear end of the outer case,the exa'et construction and mode of. operation being .fully explained hereinafter, and, fifth, the pro- 0 vision of a means wherebythe rudder is maintained in a central position. These objects I accomplish by the mechanism illustrated in the accompanying drawings, in which-- Figure li's a plan view of my improved au- 5 tomobile torpedo'with the top of the casingremoved. Fig. 2 is a longitudinal sectionalview thereof. -i Fig. 3 is atop view of-motorcase intact, showing more fully the mode of .operating the rudder. Fig. 4 is a transverse sectional view taken in line a: m, Fig. 1. Fig. 5 is a front view of a train of gears to be 0perated with a clock-spring for explodin' the explosive charge at any given time. ig. 6 is a side'sectional view of the slow gear, adjustable pin, and switch -lever connection, showing the mode of operating the same.

.Similar letters and figures of reference indicate the several parts throughout the several views.

In the accompanying drawings, A indicates an outer shell or case. The said case is made in two parts 1 and 2. vided upon each side with outwardly-projecting fins or flanges 3 and 4. The said flanges serve for two purposes-first, -to form' a seat for the upper half 1 and to whichthe upper The lower half 2 is prohalf is bolted by the bolts-5, and, second, to

form fins to hold the torpedo level when in the water and obviating all danger from turning over. The upper half or section 1 is also provided with small flanges 6 and 7,-and flexible packing is placed between the flanges to make a water-tight joint when the sections 1 and 2 are bolted together. The lower half of the case is provided with the bulkheads 8 and 9, and between the same and near the bottom of the lower half of the shell rests the explosive shell B, in suitable bearings C2, se-

provided with a spring-bolt D, operating in suitable bearings 10 in the lower half of the outer shell. Its object will be fully explained inthe operation.

E indicates a storage battery whichis placed .between'the partitions 9' and 12 to retain the same in position. I mention storage battery, but any other device may be used which will give sufiicient current to propel the torpedo. i y

F indicates an electricmotor, which may be of any construction to rotate the propeller-. shaft G. The said shaft rotates in suitable bearings H, secured attthe stern end of the points, come in contact with each other.

lower half of the outercase and is provided upon its outer end with a suit-able propeller I. The front end of the said shaft may be attached direct to the motor-shaft or may be separate and geared one to the other with spur-gears of diiferent sizes to increase the velocity of the propeller-shaft above that of the motor.

I will now give a description of the rudder or steering mechanism. v

The upper half of the outer shell or case A is so constructed at the stern end as to form a fiat deck or platform K. This deck is used for the rudder mechanism. The rudder L is composed of the bar M, which is horizontal and bent in the center to form a U-shaped loop N to form anopening to allow the rotation of the propeller I. The outer end is provided with the downwardly-projecting blade 0. The said rudder arm or baris pivoted on the pivot-bolt P, secured upon the deck K. The inner end of the said bar is provided with the upwardly-projecting pin Q, which passes through a slot formed in the rear end of the bar R,which is pivoted upon the standard S, secured upon the deck K in a center line. The inner end is placed between two springs 13 and 14. The said springs are secured at their rear ends to the standards 15 and 16. The loose ends of the springs bear against the loose end of the bar B. Any tension required can be placed upon the springs bearing against the loose end of the lever R.

The torpedo-shell Bis separate and distinct from the outer case A and tapers from the center toward the ends, the front end being the smaller, and it may be solid and also may be screwed within the shell. The large or rear end is screwed within the cylinder for the convenience of loading the same. The front end is provided with two tapering carbons 17 and 18, so placed that their inner sides, near the The large ends, which are secured within the cylinder-head, are insulated from the head to prevent all accident when placing the shells within the outer case and making the connections with the battery. Wire connections are made from the carbons to the switchplates 19 and 20. These plates, when secured to the head, are also insulated from the shell and from each other.

21 indicates an electric switch-lever pivoted upon a suitable bracket 22. The lever composing the switch is placed in such a position that the loose end lines with the plunger-bolt D. The electric wire 23 connects onepole of the battery to the carbon-point 18. The other pole of the battery is connected to the switchlever 21 by the electric wire 24. '(Shown fully in Fig. 1.) I

It willbe readily seen by those skilled in the art that should the switch-lever 21 be forced in-contact with the switch-plate, the electric current through the carbons is closed, causing electric heat at these points of contact, exploding the charge placed within the shell 13. The crank-lever 25 is connected to the switclnlever 21 by a rod 26 or any suitable connect-ion. The lever 25 is pivoted upon a suitable bracket 27, secured to the partition 12, and is operated by the chain of gears or clock-motor J, which is of any form of that by winding the clock mechanism'the clockworks are set in motion, and to cause.

the explosive charge to be exploded at a determinate time the pin 30 is slid in the slot in the body of the slow gear until it is opposite the time desired inscribed upon the face of the gear, when the motor of the torpedo is set in motion and the torpedo glides on its way toward the obstruction, and when the pin 30 comes in contact with the lever 25, which in turn pulls upon the rod or connection 26 and causes the lever 21 to be brought in contact withthe plate 20 of the carbonpoint, which causes an electric circuit, which causes the points to ignite the explosive charge to explode the same. It will also be seen that with this time mechanism in connection with the striking mechanism my torpedo may be caught in the protective nets used to surround vessels and not being exploded by said contact will at a certain time be caused to explode by the time mechanism. The battery also supplies a current for the electric motor, which is put in motion by the switch-lever 32 or button attachment.

The shells or torpedoes B are loaded and kept ready for use placed-in a suitable magazine, also the storage batteries. When it is necessary to use the torpedoes, all that is necessary to do is to place the battery E in its proper position, then place the torpedo in its bearings C in the partitions 8 and 9, attach the wires 23 and 24, and also the wires 33 and 34: from the battery, to the motor F. The upper half 1 is then screwed down upon the lower half 2 by the screws 5. It is then ready for operation. It is then placed in the water and pointed toward the object to be destroyed. The motoris then started by the button or lever 32, which conveys motion to the propeller I through the shaft G, forcing the torpedo through the water in a straight line to the object.

Having fully illustrated and described my invention, what I claim as new, and desire to secure by Letters Patent, is
